Great support and easy to assemble!
Really can't complain about anything about this chair, it was delivered quickly, packaged very securely and very easy to put together with simple instructions. I work from home and am older with multiple joint problems and this chair has many different ways to be adjusted that really help, especially if I'm extra achy or sore. I really like how the arm rest can be angled so that I can access my keyboard at my desk ergonomically and the arms can be lifted up and out of the way all together so that I can position myself closer to the desk when needed. A really nice chair for a great price.

Great Chair, But Armrests Are a Nuisance
This ergonomic office chair has a lot going for it. The mesh back is comfortable and breathable, the adjustable lumbar support is excellent, and the 3D headrest is a welcome addition for long workdays. The rocking function is also a nice feature to have. Overall, the chair is very comfortable and supportive, and seems well-made with the SGS Class 4 gas cylinder.
However, there's one glaring flaw that constantly annoys me: the armrests. While they are 3D adjustable, meaning they move up and down, forward and back, and side to side, there's no way to lock them in place. This means that every time I shift in my seat or even just slightly bump the armrest, it moves. It's incredibly frustrating to constantly be readjusting them. It disrupts my focus and makes it hard to find a truly comfortable and consistent position.
If the armrests could be locked, this chair would be near perfect. As it stands, this one issue significantly detracts from the overall experience. If you're someone who fidgets or moves around a lot while sitting, I'd seriously consider whether you can live with armrests that constantly need readjustment. For me, it's a daily annoyance that makes me question whether I'd buy this chair again.

Great Chair
I was needing an affordable ergo chair and have tried quite a few. For this price range, you can't beat the quality of this piece. Adjustable lumbar support, arm rest height perfect and cushioned. The head piece is nice, but just not for me. Nicely rocks for those who can't sit still. Easy to assemble by yourself (~20 min) using common sense. The only reason I did not give it 5 stars is the seat is made more for someone wider, as I someone feel like my hips are dipping inwards (I am also very narrow). Got a more solid butt pad, and it's perfect. Also! I didn't even need to put on my lumbar support pillow, as the lumbar support is perfect for me!
Definitely recommend!

Stylish, Ergonomic
Stylish, ErgonomicI’ve been looking for a white office chair that doesn't just look good but actually supports my back. This chair exceeds expectations! The split-back design provides amazing lumbar support that moves with you. The mesh is breathable and high-quality, and the cushion is firm yet comfortable for long hours of sitting. Setup was straightforward, and the build feels very sturdy. Highly recommend if you want to upgrade your home office setup!
